To all 'whom t may concern:

Be it known that I, Anvm EMANUEL STEN- nnne, a citizen of the UnitedStates, and a resident of Reed City, in the county Iof Osceola and Stateof Michigan, have 1nvented certain new and useful Improvements inTransmissions, of which the following is a specification.

My invention is an improvement in transmissions, and has for its objectto provide a simple, economical and eliieient transmission especial-lyadapted `for motor vehicles.

In the drawings:

Figure 1 is a top plan view of the improved transmiion, with parts insection;

Fig. 2 is a rsection through the transmis-1 sion Fig. 3 is a section onthe line 3-3 of Fig. 1, looking in the direction of the arrows a jacenttothe line.

The present 'embodiment of the invention is arranged within a housing 1'of lsuitable construction, and the engine or driving shaft 2 has itsend received within the -h'ub z3 of a inion or ear wheel 4:, the saidhub being/ )ourna'le'd -ina bearing 5in fthe fe'd offlthe housing, aball bearing 6 being interpsel 1"" between the bearing 5 and the hub.

The driven shaft 7 is arranged in alinement with the driving shaft, andsleeves 8 and 9 are mounted upon this driven shaft 7. The gear wheel 4has an axial recess in the end remote from the driving shaft, whichreceives the adjacent end of the sleeve 8. and the end of the shaft 7remote from the sleeve 8 has a bevel pinion 10 which meshes with thebevel gear wheel 11 of the differential of usual construction.

A ball bearing 12 is arranged between the sleeve 9 and a bushing 13which is held within a bearing nipple in a web 14 within the housing,and a nut 15 is threaded into the inner end of the bushing. Gear wheels16 and 17 are jonrnaled loosely on the sleeve 8 and a gear wheel 18 isjonrnaled loosely on the sleeve 9. The gear wheels 1 and 16 are adaptedto be connected tothe sleeve 8 by means of a clutch element 19 which issplined upon the sleeve 3 between the gear wheels 4 and 16. and thesegear wheels. as shown, have. clutch sections adapted to cooperate withthe ends ot' they sliding section 19 to connect either gear wheel totht` -drove.

As shown in Fig. fl. four keys or splines 20 are provided for connectingtht` .slidingr element to the sleeve. and the sliding element haslongitudinally extending grooves for receiving the splines or kevs. Asecond sliding element 21 is arranged between the gear wheels 17 and 18for connectin the said gear wheels in alternation to the s eeve 9, andthis sliding element is splined' u on the sleeve 9 in the same manner asthe s iding elementA 19 is splined upon the sleeve 8 by keys or splines20. Each of these sliding elements 19 and 21 is provided with' anannular groove which is 'engaged by the arms 22 of a fork on an arm 23and 24, respectively, the arm 23 being rigid with the sleeve 25, whilethe arm 24 is rigid with the rod 26.

The sleeve 25 is mounted on the rod 26 a' d both sleeve and rod are'movable Iongtu inally independently of 'ea'ch other by suitablelmechanisml arranged adjacent to the driver. Thus either gear 4, 16, 17or 18`may be connected with its adjacent sleeve.

yA counte haft 27 is" joui-'naled in bearings 28 in theerid of thehousing and in thfweb 14s: Upon tfhis 'countersh'aft lis arranged asleeve 29, and this sleeve is ai wheissaei smreal-t e sur wires "beitgof comparatively great length, as shown. The gear wheel 30 meshes withthe gear wheel 4, the gear wheel 31 meshes with the gear wheel 16 andthe gear wheel 32 meshes with the gear Wheel 17 and also with a gearwheel 33 on a shaft 3+ jonrnaled in bearings 35 on the web 14. Thisshaft 34 carries also a gear wheel 36 which meshes with the gear wheel18. The sleeves 8 and 9 are rigid with the shaft 7, being keyed thereto,as shown in Fig. 2.

In operation, with the parts in the posi tion of Figs. 1 and 2, theengine or driving shaft rims free without affecting the driven shaft.The gear wheels l and 30. 16 and 31, 17 and 32, 32 and 33, 13 and 36 arealways in mesh. When it is desired to run upon the low speed, the rod 26is moved in the direction to cause the sliding element 21 to clutch thegear wheel 17 to the sleeve 19 and to the shaft 7. Now the driven shaftis driven through the gears #30, l7-32. and since the gear 30 is largerthan the gear -i and the gears lT larger than the gear 32. low speedwill be obtained. 'l`o obtain the nternndiate speed the gear wheel I7 isreleased. and the gear wheel 16 is connested with the driven shaft. Thedriven shaftA i now driven b v the gears Ylie-30. 11i-31, and since theygears 16 and 3l are ot' the sinne size, n higher speed will beohtziined. To obtain the high speed, thegear 1G is released :ind thegear 4 is connected with the driven shaft, and the drive is now direct.To reverse, the gear 4 is released and the gear i8 is connected with thedriven shaft. The drive. is new through the gears 4-30, 32-331 3T3-1S nnd the ieverse is obtained.

I claim: t

1. A transmission comprising alined drivin and driven shafts, nconntershaft paralFel with the said shafts, a gear wheel se cured to thedriving shaft, a gear wheel journaled loosely on the driven shaftadjacent thereto, the eountershaft having gear wheels meshing with thesaid lirst named gear wheels, clutch mechanism splined to the drivenshaft and movable into engagement with either of the first named rwheels to alternately connect the said w eels to the driven shaft, a.air of ear wheels )ournaled looselyon' the sriven s aft, a clutchsection splined to the driven shaft between the gear wheels and havingmeans for connecting eitheritothe driven shaft, a ear wheel onth'eeoiintershaft meshing IWi one of the said pair ofgearwheels, areverse shaft, and i'.,wheels on the said reverse shaft meshing with thelast named gear wheel of the @gluteishaft and4 with4 the other of thesadpadir of gear wheels ofthe driven shaft,
